those principal investigators are dave blake, 1ken edget, ralph gellter, paul mahaffey and roger weens. if i just described a few of these instruments, we can start off with everyone's favorite, which are the cameras. we have 17 cameras. you will get lots of pictures to look at. there is a camera that is mounted to the bottom of the rover. in the video where the sky crane is reeling down the rover, this camera will turn on and take a movie at five frames per second, full-color, hd resolution. this will be one of the most fantastic projects that has ever been created. with cameras on the mast to look around and find the types of rocks that we would like to do chemical analysis on. when we think something is project really promising, we can drive up closer. then we have a laser that shoots out of to a distance of 7 meters away that is that the rock, creates of spark of life, and then we look at the start, and this tells us what chemical elements are in the rock. then we deploy the arm, put it down on top of the rock, and we have a drill. this is just like a drill you buy at home depot. t
